This collection of photographs from the picture desk of Doctors Without Borders/ Médecins Sans Frontières (MSF) provides an intimate look at the experiences of MSF's patients around the world. From war and civil strife to disease outbreaks and epidemics, MSF staff have been on the front lines to save lives and respond to urgent medical needs in 2017.

MSF is grateful to the extraordinarily talented photographers who have worked alongside our medical teams to bear witness to so many moving stories over the course of a turbulent year.

More than 600,000 Rohingya refugees from Myanmar have fled to Bangladesh following a wave of targeted violence that began on August 25. Carrying few belongings but bearing many physical and psychological wounds, refugees have shared horrific stories of attacks with staff from Doctors Without Borders/Médecins Sans Frontières (MSF). Teams are treating patients for bullet, blast, and stab wounds, severe burns, and sexual violence. Other serious medical needs include acute watery diarrhea, pneumonia, malnutrition, suspected measles, and advanced obstetric complications.

Doctors Without Borders/Médecins Sans Frontières (MSF) has deployed psychosocial support teams in several areas of Mexico City, Mexico, to provide mental health care to those affected by the earthquake that struck on Tuesday, September 19. MSF teams, made up of psychologists and social workers, are working in conjunction with rescue efforts to assist families who either lost or can no longer return to their homes following the earthquake.

For more than a year, Doctors Without Borders/Médecins Sans Frontières (MSF) has been providing medical care to refugees, asylum-seekers, and migrants held in inhumane conditions in detention centers in Libya. This photo essay by Guillaume Binet, a French photojournalist and co-founder of Myop photo agency, presents a rare glimpse inside Libya's detention centers, including those where MSF provides urgently needed medical care.

Doctors Without Borders/Médecins Sans Frontières (MSF) began supporting Abs Hospital in northern Yemen in July 2015. A year later, an airstrike by the Saudi-led coalition destroyed part of the complex, killing 19 people, including one MSF staff member, and wounding 24 others. After rebuilding the hospital in November 2016, MSF resumed medical services.

Fighting between Boko Haram and militaries from the areas around southeastern Niger has led to more than 240,000 displaced people and refugees taking shelter in Niger's Diffa region. A third of the displaced people in Diffa have been forced to abandon their homes two or more times due to violence in the last few years. Around the towns of Garin Wazan and Kintchandi, many of the tens of thousands of people who fled Bosso, a town near the Nigeria border last June, have sought safety.

Violence has spread into parts of southern Central African Republic, and communities that were relatively calm until March 2017 are now caught in the crossfire. Villages have been burned and people have been attacked and displaced. Doctors Without Borders/Médecins Sans Frontières (MSF) works in several areas, including Bambari, where communities are cut off from medical care and people have fled their homes and livelihoods.

More than 7,500 migrants and refugees are currently stranded in Serbia, living in overcrowded camps and informal settlements. The country has agreed with the EU to host up to 6,000 people, of whom only 3,140 live in facilities adapted to winter. In Belgrade, around 2,000 young people, mainly from Afghanistan, Pakistan, Iraq, and Syria, currently sleep in abandoned buildings in the city center, while temperatures plummet to as low as -20°C or -4°F.
